Incident Report

Summary AI Generated

Amazon Web Services experienced increased error rates in the EU-CENTRAL-2 (Zurich) region, primarily caused by substantial error rates for PUT and GET requests to Amazon S3 due to issues with a subsystem responsible for assembling objects from bytes in storage. The incident affected dozens of AWS services including EC2, Lambda, CloudWatch, and SageMaker, with other services that rely on S3 also experiencing disruptions, though existing EC2 instances remained unaffected. Engineers implemented mitigations and observed improvement in error rates, with early signs of recovery appearing after 48 minutes.

We are investigating increased error rates in the EU-CENTRAL-2 Region.

We are seeing early signs of recovery and continue to monitor and work toward full recovery.

UPDATE about 6 hours ago - at 03/07/2026 08:17PM

We can confirm substantial error rates for PUT and GET requests to Amazon S3 in the EU-CENTRAL-2 Region. Engineers engaged immediately based on automated alarming. We have triangulated the issue to a subsystem responsible for assembling objects from bytes in storage. We have begun implementing mitigations, and are observing some improvement in error rates. We continue to work to identify the root cause, and are working on multiple parallel paths to fully mitigate the issue. Other AWS Services (such as EC2 launches) that rely on S3 are also affected by this issue. Existing EC2 instances are unaffected by this issue. We will provide another update by 12:45 PM PST, or sooner if we have additional information to share.
